Detailed explanation-1: -When a glass rod is rubbed with silk, it acquires a positive charge, means it is deficit of electrons i.e, electrons move from glass to silk. So glass rod becomes positively charged and silk rod is negatively charged.

Detailed explanation-2: -Rubbing a glass rod with silk transfers electrons from the glass to the silk and the deficiency of electrons on the glass makes the net charge on the glass rod positive. We know that there are positive charges and there are negative charges. Same sign charges repel and like sign charges attract.

Detailed explanation-3: -Since the glass rod acquires a positive charge, this means that it is deficient in electrons. Since the rod was rubbed by the piece of silk, the silk is what now collects the electrons. The silk now has an excess of electrons which means that the silk is now negatively charged.

Detailed explanation-4: -When silk is rubbed with glass, glass happens to lose electrons easily, and silk grabs them away from the glass atoms. So, after rubbing the glass becomes positively charged and the silk becomes negatively charged.
